How to point a Registro.br domain (Cloudflare)

Why Registro.br alone isn't enough

You bought your domain (e.g., yoursite.com.br) on Registro.br, but just having the domain doesn't put your site online. You need to point the domain to where your application is hosted — and the most robust way to do that is by handing DNS management over to Cloudflare.

What nameservers are

Nameservers are who "answer" for your domain on the internet: they tell which server the visitor should go to when they type your address. By default, your domain uses Registro.br's own nameservers. By switching them to Cloudflare's, you start managing all DNS through Cloudflare, with more speed and features.

Why go through Cloudflare

Faster DNS: Cloudflare has one of the fastest DNS networks in the world.
DDoS protection: your site sits behind Cloudflare's protection.
CDN and cache: content delivered faster to the visitor.
Easier HTTPS: SSL certificate managed automatically.

Every Square Cloud app already runs behind Square Cloud's Cloudflare edge (WAF, DDoS mitigation, TLS). Moving your DNS to a free Cloudflare account is recommended for fast DNS changes and apex flattening. Custom domains require the Standard plan or higher.

Step by step: pointing Registro.br to Cloudflare

Create a free account on Cloudflare.
Click Add a Site and enter your domain (e.g., yoursite.com.br).
Cloudflare will scan your records and provide two nameservers (e.g., nina.ns.cloudflare.com).
Access the Registro.br panel and open your domain.
Go to Change DNS Servers.
Replace the current nameservers with the two provided by Cloudflare and save.
Wait for the nameserver change to propagate (up to 24-48 hours) and check on dnschecker.org (type NS) that the Cloudflare nameservers show up before attaching the domain on Square Cloud. A domain left pending for more than 24 hours is removed and must be attached again.

Pointing to your application on Square Cloud

With DNS already on Cloudflare, just create the records that point to your application on Square Cloud. The full step-by-step for DNS and CNAME records is in How to set up your own domain.

Still not working?

Switching nameservers isn't instant. If the site still won't open, it's usually a matter of propagation — see Why hasn't my domain propagated yet?.
